Details

"Fallout!" The Gold Team of the X-Men travels to Asteroid M in an undetectable space ship, desperately trying to safe their teammates, before the Russians destroy Magneto’s base with a plasma cannon. Aboard the Asteroid Xavier helplessly sees his Blue Team brainwashed by Moira into following Magneto, though some of them seem to realize that something is wrong. Magneto still suffering from injuries received by Wolverine grows more and more dependent on Fabian Cortez‘ cures. When the Gold Team arrives they have to fight both their teammates and the Acolytes, but soon the X-Men remember themselves. Magneto stops the battle, wanting only Xavier, but then he collapses. Moira understands that Cortez has only boosted his powers to make him feel better, In the meantime Cortez has escaped, he intends to turn Magneto into a martyr and inspire mutants all around the world to follow him. As the plasma canon is fired the X-Men hurry to their spaceship. They want to rescue Magneto and the remaining Acolytes as well, but they prefer to stay aboard Asteroid M and die as it goes down.
